What do YOU do for a living, and how do you scam and cheat and harm people in order to increase your profits, eh? Because since you are so quick to assume this in other people, it must be because it is what you would do yourself.

Actually my interest in researching all this came about after 3 people in my immediate family died shortly after receiving flu shots.
